Patent SE-8004161-L (SE)
Inventor: HESSE P
IPC: C12N1/00
Filed: 1980-06-04
Abstract: To establish predetermined humidity levels within a sterile treatment chamber, and maintain sterility, water, preferably deionized, is conducted to an evaporator outside of a container defining the treatment chamber, to be there heated to superheated steam, for example in the order of 300 DEG  C., and conducted to a bypass duct (1) in atmospheric communication with the treatment chamber (10), for mixing with the atmosphere within the treatment chamber. Preferably, the treatment chamber is surrounded by heat exchanger elements, such as electrical heating wires and/or cooling coils, the heaters being controlled to rapidly heat the treatment chamber to a temperature in the order of 180 DEG  C. during pauses of treatment for sterilizing the interior of the container, and/or maintaining temperature levels at a desired treatment level in operation. Additional gases to establish controlled atmospheres can be admitted to the interior of the treatment chamber, preferably after having passed through a heat exchanger for establishment of a desired temperature level.

Abstract: A process and electroplating bath for use in electrodepositing nickel on a base where the electroplating bath includes a coumarin compound and an aryl hydroxy carboxylic acid compound, such as salicylic acid, present in a combined amount effective to provide a ductile, self-leveling nickel deposit. The bath may further include hexyne diol and/or a material selected from the group consisting of primary acetylenic alcohols and adducts of primary acetylenic alcohols, as well as mixtures thereof. It has been found that excellent leveling and physical properties can be maintained utilizing such a bath, while at the same time, the usual coumarin concentration level can be reduced significantly and process life can be dramatically extended. In addition, additives such as butyne diol, and/or aldehydes such as formaldehyde and chloral hydrate may be utilized. It has also been found that corrosion resistance is substantially improved utilizing the process and electroplating bath of the present invention.

Abstract: A force-measuring device for contactless measurement of the feed force transmitted from a drive machine via the drive shaft (4) onto a rotating tool (9) is proposed, in which the tool (9) is connected in a force-closed fashion to the drive shaft (4) via an elastic springing element (6). In order for the offset which occurs due to the bearing play not to act as a measurement error, a measuring ring (13, 14) is rigidly connected in each case both to the drive shaft (4) and the tool (9). Depending on the particular distance between the two measuring rings (13, 14), a sensor (15, 16) generates a measurement signal corresponding to the feed force. The bearing play has no effect on the distance between the two measuring rings (13, 14).

Abstract: A heating device, particularly an auxiliary vehicle heating device, in which there are disposed, a first temperature sensor at the inlet, and a second temperature sensor at the outlet of the heating device. The outputs of the two temperature sensors are connected with a circuit, so that the operating condition of the heat exchanger of the heating device can be constantly monitored. For the purpose of early detection of a tendency towards overheating of the heating device, appropriately, the temperature differential between the two temperature sensors is determined, and, based upon a predetermined threshold value, the heating device is turned off, if necessary, in order to prevent resultant damage. The outputs of the temperature sensors can also be integrated with a control unit for the performance of control functions and, based upon different switch points, control operation of the vehicle blower, the heating output, and/or the heat exchanger temperature.

Abstract: A pressure fluid operated ride leveler which adjusts the actual level of a vehicle body relative to a vehicle axle to a desired level, includes a pressure fluid source and a pressure fluid sink, pressure fluid chambers which support the vehicle body, and a pressure fluid conduit connecting the pressure fluid chambers to either the pressure fluid source or the pressure fluid sink. First and second controllable valve mechanisms are disposed in the pressure fluid conduit. The second valve mechanism is, e.g., a controllable throttling valve, capable of reducing the diameter of the pressure fluid conduit. Both the first and second valve mechanisms are actuated by a control unit. The control unit actuates the first valve mechanism to connect the chambers to the pressure fluid source or the pressure fluid sink based on the difference between the actual level of the vehicle body and the desired level. When the difference between the actual level and the desired level becomes less than a predetermined value, the control unit actuates the second valve mechanism, thereby reducing the diameter of the pressure fluid conduit and slowing down the delivery or withdrawal of pressure fluid. In this way, overshoot of the desired level is avoided and the number of adjustment steps is reduced.
